Think...... what is 7 and 21 both divisible by?
COUGH they're both divisible by 7.... so divide both numbers by 7, and stick them in they're rightful places
The mean is the average.
To solve for the average we add all the numbers up and divide by how many numbers there are.
21, 23, 25, 25, 26, 28, 28, 28, 31, 33.
268 total, now divide by how many numbers there are.
268/10
Your mean is 26.8
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° =
=
( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° =
=
( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )
Answer:

Here,
represents temperature and
denotes rate of chirping per minute.
Step-by-step explanation:
Let
represents temperature and
denotes rate of chirping per minute.
At
°F, a certain insect chirps at a rate of
times per minute.
Take 
At
°F, they chirp
times per minute.
Take 
Slope intercept form:


C x=4y can no be true.
x=4y, total phonographs are 5y
5y cannot be 24 if y is an integer.
